Natural-gas metering advance applies microthermal technique
Sensirion claims a breakthrough for its microthermal technology. The Sensirion SGM6200 module covers natural gases in group E with up to 25% hydrogen content at a current consumption below 10 µA.
New environmentally friendly technologies, such as power-to-gas and biogas production systems, will change requirements for the entire natural gas industry, including gas metering, a problem Sensirion has been working on for several years; its technology to measure thermal gas characteristics has been developed in-house.
Sensirion plans to commercialize this technology by adding the SGM6200 series to its current product portfolio of SGM6000 modules. The sensor company believes that the SGM6200 series meets both current and future market requirements. One single module covers natural gases in groups H and L and E (as defined in EN437) as well as natural gas mixtures, including non-conventional fuel gases with up to 25% hydrogen content. The SGM6200 family will output temperature-compensated volumes of natural gas, aligned with today’s most widely used billing systems for natural gas. Current consumption below 10 µA enable Sensirion’s customers to design very competitive, cutting-edge meters for natural gas.
Currently, Sensirion plans to make samples available by February 25, 2018. Start of production for the G4 module of the SGM6200 family is planned for Q3 2018. By assessing additional physical properties of natural gas, the SGM6200 series paves the way for realizing Sensirion’s vision of direct energy content monitoring of natural gas in gas meters.

Over 1 million MID-approved smart gas meters with Sensirion’s microthermal gas meter modules are currently being operated in Europe by over 50 utility providers, the company adds. Numerous pilot projects are running at leading utility providers in the Middle East, Asia, Europe and America with the goal of establishing Sensirion’s gas metering technology worldwide.
The microthermal sensing principle is a static metering technology featuring noiseless operation. Thanks to their compact size, Sensirion gas meter modules allow the design of very compact and cost-efficient gas meters for easy installation in the field, even in very confined spaces. Due to ultra-low power consumption, one single AA Li/SOCl2 cell is sufficient for more than 15 years of module operation.
